American Racing Headers 1 7/8 W/cats (just in case) With Borla S Type II exhaust! Awesome!!!!

Not So Fast

Probably be about 3 more weeks But I did talk with the DynoTuner yesterday and am pretty committed to going that way after install.
After spending the money for the headers it only makes sense to maximize the effect right.
I'll post numbers no matter which way they go

You're car is gonna be nice with those Kooks buddy!!

Not So Fast

I will never match the "speed of light" that your Vette has had cast upon it Steve, what with the mods you've done over the last couple of months makes mine seem insignificant
Your help is appreciated

HOXXOH

If you're not racing the car, there is no need to squeeze the last bit of power out of headers unless the dyno sheet number is important to you. Your butt dyno isn't calibrated enough to notice a difference, so throwing a dart is a workable method to make a selection.

If you are wanting max power, then plan out all the mods before you purchase anything.

Happy with the Kooks LT headers, catted X Pipe, running into the NPP. Can't go wrong with any of them.

I had ARH's installed on my 08 a few years ago at a performance shop and they leak at all 8 pipes and as of today they will not replace them...Bottom line ARH SUCK!!!

Good to know! I'll scratch them off of the list!

All great choices. Really, they all are. We carry all those brands but let's add these to the confusion.

You should be very close if you are a manual, just slightly lower if an auto

Virtually all numbers I've seen out here are within +/- 5. The temp, humidity, type of dyno, etc. all play with the numbers you get.

I could feel a difference on the drive home, but don't notice it now. I really do like the louder sound, I had to hold my ears during the dyno testing. But with the NPP closed, it's barely louder than stock.

It was just Daytona race week here, and I impressed a few fans with a 2nd gear punch at 30 with the NPP open (smoking the tires for about 2 seconds, the speedo at about 70, while still doing 30). Instantly, my radar detector was going berserk, so I put it back in quiet mode and behaved the rest of the way home.
